Rotation

-a transformation that rotates or turns a figure on a point

Function Rules

  • 90 degrees counter clockwise: (-y,x)
  • 90 degrees clockwise: (y,-x)
  • 180 degrees clockwise/counter clockwise: (-x,-y)
  • 270 degrees clockwise: (-y,x)
  • 270 degrees counter clockwise: (y,-x)
  • When the y or x variable is negative, it turns to a positive corresponding to its rule.
  • When the y or x variable is positive, it turns to a negative corresponding to its rule.
